Marcellus shale gas wells in Pennsylvania continued to see significant production increases in 2011. During the last half of 2011, the output was up over 40% from the same reporting period in 2010. New data come from the PA Department of Environmental Protection, showing over 2,200 producing wells, which is an increase of more than 500 since the first half of 2011.
Drilling companies reported producing 67 billion cubic feet of natural gas in Washington County during the six months, up from 45.9 billion cubic feet during the previous half year. Greene County wells produced 67.8 billion cubic feet during the reporting period, up from 51.1 billion cubic feet. Washington County gained 75 producing wells, reaching 353 total. Greene County gained 49 producing wells for a total of 283.
Gas production in southwestern Pennsylvania more than doubled during the last six months of 2011, compared with the same period in 2010. It went from about 82 billion cubic feet to 171 bcf. Statewide production followed the same pattern. It increased to 607 bcf from 256 bcf during the second half of 2010.
Condensate production also saw a substantial, 52 percent increase ending at 487,438 barrels. McAdoo Unit 2H well of Range Resources produced the most condensate at 30,702 barrels during its 155 days of production.
Of the southwestern Pennsylvania wells that were producing gas for the entire six months, the top five were all in Greene County . The most productive was EQT’s Cooper 590387-A well in Morris Township which yielded almost 1.9 bcf of gas during the last six months of last year for an average of 10,085 mcf per day. In southwestern Pennsylvania, the best daily production from wells three months old and older came from Range Resources’ Phelan Unit 4H, which produced about 14,992 mcf of gas per day.
